Description

The The present invention relates to a solid salt preparation with improved Handling, which is a mixture of a salt of a halogen-containing oxyacid and a solvent contains. Furthermore, the present invention relates to a process for the preparation such salt preparations and their use, in particular in stabilizer compositions for halogen-containing polymers.

As is known, tend halogen-containing plastics under thermal stress during the Processing or in long-term use to unwanted decomposition and degradation reactions. In the degradation of halogenated polymers, especially in PVC, arises Hydrochloric acid, which is eliminated from the polymer strand, resulting in a discolored, unsaturated Plastic results with coloring polyene sequences.

Especially in the case of shaped bodies, exposed to light, changing temperatures or other external influences are, it comes with increasing service life to changes the color and the material properties, which may be up to for unusability of the molding can progress.

Various Stabilizer systems have been proposed to halogenated polymers with regard to long-term damage to stabilize by the action of light or heat. So be For example, in the prior art systems described the perchlorate salts for the stabilization of halogen-containing polymers.

adversely However, the systems described often have an effect, that not in all applications the desired stabilization effect with regard to the stabilizing Polymer can be achieved. Often the stabilizing effect remains behind the requirements.

Problematic the use of perchlorate salts continues to have an effect Such sensitive oxidants are usually very careful have to be handled for damage to health to persons or damage of material, for example due to explosions, to avoid. For this reason, users often have reservations about the Use of perchlorate salts in stabilizer compositions. Therefore, different solutions proposed as such perchlorate stabilizer compositions can be improved in terms of their handling.

For example EP-B 0 457 471 describes a stabilizer composition, containing perchlorate, calcium silicate and calcium carbonate. to Preparation of the stabilizer compositions described is an aqueous one solution of sodium perchlorate with calcium silicate or a mixture of Calcium silicate and calcium carbonate mixed. Problematic acts in the described stabilizer compositions that they still contain crystallites of sodium perchlorate. These Crystallites can, as already described above, if necessary in handling Raise problems. About that In addition, such stabilizer compositions can be found in some make not sufficiently homogeneous in a halogen-containing to be stabilized Incorporating polymers. Furthermore, the presence of a carrier material limits often the stabilizer effect compared to other stabilizer compositions one. About that In addition, the calcium silicate used in the case described has a high Mohs'sche Hardness up, whereby processing plants may be permanently damaged can.

It There was therefore a need the efficiency of stabilizer compositions containing a salt of a halogen-containing oxyacid included, to improve. In particular, there was a need that capacity of stabilizer compositions containing a salt of a halogen-containing oxyacid included, in terms of and the thermostability of the too stabilizing halogen-containing polymers to improve.

by virtue of the problems of handling perchlorate salts or of preparations based thereon a need for such preparations containing a salt of a halogen-containing oxyacid contained in a packaging that presents a danger in handling significantly reduced with such perchlorate salts.

Although preparations are known in the prior art comprising perchlorate salts in the form of a liquid solution in water or for example butyldiglycol, such liquid preparations are in many cases limited in their applications, for example in stabilizer compositions for halogen-containing polymers. In many cases it corresponds to the desire of the formulator sol Such stabilizer compositions that corresponding perchlorate salts of the stabilizer composition in solid form, ie as solid salt preparations, are added in order to have the greatest possible freedom from formulation when adjusting the consistency of the stabilizer composition. Liquid perchlorate salts often do not meet this desire.

Of the The present invention is therefore based on the object such solid salt preparations and stabilizer compositions based thereon and methods for their respective manufacture available put.

Be solved the objects underlying the invention by salt preparations and stabilizer compositions containing such salt preparations contain, as well as procedures for their production, as under of the following text are described.
